Relevant Information:

As per original description: “Very light or pale brown, lower or under surfaces more or less whitish. Upper surface of head and back sprinkled with dark grey dots. Band of dark dots along lateral line and broader one along lower side of trunk and tail parallel. Iris greyish, also maxillary barbell, other barbells whitish. Outer edge of adipose fin dusted with dark grey dots. Caudal dark grey. Other fins pale or whitish.” This is a small and graceful looking species, which reminds me (Grant 2009) of species of the South American pimelodid genus Pimelodella Eigenmann & Eigenmann, 1888. The lack of any semi-ocellus, the thin dark band across the lateral line, and large gap between the small supraoccipital process and basal bone of the dorsal fin spine differentiate this species from all the others. (Grant 2009). Habitat: Adults occur in medium to large-sized rivers and flooded fields. Feed on insect larvae, fish scales and other fish body parts, as well as plant debris. Breeding habits and seasonal movements are unknown. Oviparous, distinct pairing possibly like other members of the same family
